Esther told him of the doctor's visit and the instructions he had given, and then handed him Ruth's letter, which he read in silence.
"I don't like the look of it," he said. "I hate mystery, and I cannot decide immediately whether it ought to be kept from Mr. Cohen."
"Oh, father," cried Esther, "Ruth will never forgive me if I betray her."
"I don't think it is a question of betrayal," said Mr. Moss. "She tells you to speak to me, and you have done so. I take the blame on myself, whatever happens. My dear, you are not old enough to understand such matters, and you must leave this to me. The letter will be better in my keeping than in yours. Just consider, Esther; would you have behaved so?"
"No, father, I could not."
"There is the answer. The odd impression I spoke of was that I saw Ruth to-night in a hansom cab. I thought I was mistaken, but now I am convinced it was she. If I had known what I know now I should have followed her. As to Ruth never forgiving you, what will Mr. Cohen's feelings be towards you when he discovers that you have acted in a treacherous manner towards him and his wife? Ruth is very little older than yourself, and I am afraid cannot discriminate between right and wrong; she must not be allowed to drag us into a conspiracy against the peace of the family."
Esther was dismayed; she had not looked upon it in this light.
"Was Ruth alone?" she asked, in a faltering voice.
"No, she had a gentleman with her. It is a bad business--a bad business. I intended to return to Portsmouth to-morrow, but now I shall remain till the matter is cleared up."
"Shall you speak to Mr. Cohen to-night, father?"
